Hi Christian and Ingo,
Thanks for your interest in using the snap! Last months work has been ongoing to make OH2 work on ubuntu-core as a snap. There is some good news and … there are some rough edges / things that need to be worked out. In short the snap is probably not the best choice for most users yet (some work in progress).
If you are running Ubuntu 16.10, everything should work fine. Like other programs, you can install OH using the command line with:
$ snap install openhab
If you are using ubuntu-core instead of Ubuntu 16.10, e.g. installing the image on a raspberry pi, I expect most bindings will work (a lot more testing is needed to confirm this though), but there are some limitations when you would need USB devices or GPIO. If you do want to hack your way around this issue to make use of a zwave controller or something, I will add some pages to the manual in the coming week.
Canonical is giving great support to this project (many thanks Ondrej!), but I cannot give an estimate when this issue is solved. Good thing is that it involves multiple projects, e.g. nextcloud box, so I am quite confident it will be solved in the coming months.
Best regards,
Roeland
PS1) info about installing Ubuntu-core: https://developer.ubuntu.com/core/get-started
PS2) The raspberry pi image of Ubuntu core will ask you to make an account with Ubuntu, set up your device with keyboard and screen. Thereafter you log on to your pi via ssh.
PS3) once the snap is installed, OH will start automatically. You can use a browser to find OH at http://:8080/start/index
